Desirable Pore Connectivity Effects in Multiscale Interactive Cobalt Centers with Asymmetric B/N‐Coordination Carbon for Promoting Zn‐Air Batteries

Advanced Science, EarlyView.
A bicontinuous constructed cobalt active centers/asymmetric B/N‐coordination carbon catalyst is developed, which the ZAB assembled with CoBNPCF‐900 air cathode exhibits ultralong stability (1706.6 h). The permeability simulations indicate that the catalytic active site is highly exposed to the electrolyte, guaranteeing a high catalytic efficiency ...
